"The writers just nailed it," Smulders says. "It's so fun and they just made it so funny, but so lyrical at the same time."

The woman behind Robin Scherbatsky also revealed that the cast recently read through some of the episodes that will roll out later down the road, marking the end of the series. So how were they? In a word…

"They're big," she previews. "The episodes are very big."

Just to speculate, big for How I Met Your Mother could mean Ted (Josh Radnor) finally, finally meeting the mother, for real, face-to-face during Robin and Barney's (Neil Patrick Harris) wedding weekend. Or big for the CBS comedy could mean a teeny-tiny reveal that will be setup a bigger moment later on in the season.

And in regards to that other huge show she's attached to, Smulders' future with S.H.I.E.L.D. is still in helipad status, as in, up in the air. When we asked if her character Marie Hill would make another appearance in season two of the ABC hit series, Smulders insists she's in the dark about that.

"We'll see. I don't know. I'm just finishing this season of How I Met Your Mother and then we'll see," she tells us. "I don't know what the next year's going to be. I'm just trying to get through this one!"

How I Met Your Mother airs Monday nights on CBS, and S.H.I.E.L.D. flies into action every Tuesday evening on ABC.
